The second day the work went on more desperately still. But Smithers' work in releasing men was telling. There were fifteen hundred governors, or reducing valves, or autocratic cut-outs in operation now. And fifteen hundred men were released from the machines, which had to be kept going to keep the city alive. With that many men, intelligent mechanics all, Tommy and Smithers worked wonders. Smithers drove them mercilessly, using profanity and mechanical drawings instead of speech. Denham withdrew twenty men and labored on top of one of the towers. Toward sunset of the second day, vast clouds of steam bellied out from it at odd, irregular intervals. Nothing else manifested itself. Those irregular belchings of steam continued until dark, but Tommy paid no attention to them. He was driving the gunners of the machine guns to practice. He was planning patrols, devising a reserve, mounting thermit-throwers, and arranging for the delivery of the promised ransom at the specified city gate. So far, there was no sign of anything unusual in Rahn. Messengers from Yugna saw the captive women regularly, once every three hours. The last to leave had reported them being loaded into great ground vehicles under a defending escort, to travel through the dark jungle roads to Yugna. A vast concourse of empty vehicles was trailing into the jungle after them, to bring back the food which would keep Rahn from starving, for a while. It all seemed wholly regular. * * * * * At dawn, the remaining ships of the air fleet of Rahn were soaring silently above the jungle about the Golden City. They made no threat. They offered no affront. But they soared, and soared.... A little after dawn, glitterings in the jungle announced the arrival of the convoy. Messengers, in advance, shouted the news. Men from Yugna went out to inspect. The atmosphere grew tense. The air fleet of Rahn drew closer. Slowly, a great golden gateway yawned. Four ground vehicles rolled forward, and under escort of the Rahnians entered the city. Half the captive women from Yugna were within them. They alighted, weeping for joy, and were promptly whisked away. Evelyn was not among them. Tommy ground his teeth. An explanation came. When one half the promised ransom was paid, the others would be forthcoming. Tommy gave grim orders. Half the foodstuffs were taken to the city gate--half, no more. At his direction, it was explained gently to the Rahnians that the rest of the ransom remained under guard of the thermit-throwers. It would not be exposed to capture until the last of the captives were released. There was argument, expostulation. The rest of the women appeared. Aten, at Tommy's express command, piled Evelyn and his own wife into a ground vehicle and came racing madly to the tower from which Tommy could see all the circuit of the city.
